Settings: Make CM developer options additions respect the on/off toggle
This commit fixes the problem where, when dev options are turned off, our
CM customizations don't turn off with the rest of the options and the
dangerous option (root access) does not reset to a safe setting.

Settings: Hide Development settings when it is turned off

This commit hides the Development and Performance settings items
when the user turns off Development settings. This sets things back
to tapping x number of times on the build number to once again enable
developer settings

Development: Root for apps is unavailable if the su daemon isn't running

The superuser options are tied to the Superuser app variant we use,
which in turn is tied to the su daemon. No daemon, no menu options.
